Film type saddle type deflection member for cathode ray tube and saddle type deflection coil manufacturing method using same

The present invention relates to a film saddle type deflection member of a cathode ray tube (CRT), a deflection coil using the same, and a method of manufacturing the same. In detail, a plurality of film deflection members having a plurality of conductive wires formed in a predetermined pattern and stacked thereon In the manufactured deflection coil, the saddle type film deflection type for cathode ray tube which minimizes the number of connection terminals and facilitates the connection work of the conductors and enables the simple three-dimensional shaping to be processed in a saddle type. A member, a deflection coil using the same, and a manufacturing method thereof.

Conventionally, as a deflection device for a cathode ray tube, instead of implementing a deflection device coil by a general copper wire winding, a conductive wire is formed on an insulating film in a predetermined pattern by using a printed circuit or a printed winding technology, and the deflection device is laminated. Various methods have been proposed to implement a coil for the device.

An example of such a prior art is European Patent Publication No. EP 0 169 613 A, filed on January 29, 1986 (applicant: N. Philips). This will be briefly described with reference to FIGS. 1 (a), (b) and (c) as follows.

The saddle type deflection member is formed by stacking a plurality of insulating films having a conductive pattern of copper wire, and the saddle type deflection member 10 is divided into a first deflection member and a second deflection member. As shown in FIG. 1A, the first deflection member 11 is turned so that its distal end forms the portion 14a 15a, and the conductors 20a, 21a, 22a, 23a of the copper wire are disposed therein. Is formed. The second deflection member 12 forms a bridging member as shown in FIG. 1 (b), with the short side rims forming portions 14b and 15b and the cross rim forming portion 18. The second biasing member has copper wire conductors 20b, 21b, 22b, 23b. The first biasing member 11 and the second biasing member 12 are formed of the conductors 20a, 21a, 22a, 23a of the first biasing member and the second biasing member, as shown in FIG. The conductors 20b, 21b, 22b, and 23b are connected to each other by welding or the like, thereby forming the saddle type deflection member 10. In addition, the prior art uses polyester or polyimide as the insulating film material, and mentions various technical parameters for configuring the deflection yoke by using other film type deflection members.

According to the connection structure of the conventional film-type saddle type deflection member, the connection terminals can be formed with 4N of bias input and endturn connection members each input and output terminal according to the number of conducting wires (N amperages) on the pattern. In addition, when the deflection members are stacked in plural (M) pieces, 2M terminals are also required. In addition, the position of each connection terminal is located inside the conducting wire pattern.

In other words, there are 4N × 2M connection terminals required to manufacture one laminated deflection member. Since many connection terminals are sequentially arranged within a narrow gap, the connection work is complicated.

In addition, since the connection terminals located inside the conductor pattern need to be formed in a limited space, the size of the connection terminal must be limited, and in addition, the size of the connection terminal for reliable electrical contact can be secured. To this end, there is a drawback in that a space other than the space in which the pattern of the conductive line is formed is required.

Accordingly, since there are too many electrical connection work points of the conductor and the size of the connection terminal is limited, there is a problem in the electrical reliability after the connection work, and there is a problem that it is not easy to check the shorting point.

Accordingly, the present invention is to solve the above-described problems, in the film-type deflection member patterned conducting wire on a base film of a predetermined form, the patterned conducting wire is connected to each other without being separated separately It is an object of the present invention to provide a new saddle-type deflection member of film type cathode tube which can minimize the connection.

It is another object of the present invention to provide a method for three-dimensionally forming a film saddle type deflection member.
